In Switzerland December- 3,V 1936 1 claims. (ci. ssc-11.13). y l y I Fig. 9 is a cross sectional view takenalong 'I'he present invention relates to a ski, more particularly to a ski which is made up of a plurality of partswhich can be taken apart for facilitating transportation of the `ski and replacement of individual parts. I.

It is an object of the present invention to provide a skiconsisting substantially of a fore end motor car,y railroad, rucksack or direct carrying part and ofga rear end part and a middle partl whichrigidly yetdisconnectably interconnects said other parte.l The individual parts of the ski according to the present invention are of a size which is convenient for transportation in a by the skier.l

Another object of the present invention resides in the provision of a vdemountablerslli comprising a center part which'is substantially made of metal or other particularly hard material andvto which a wooden fore end part and a wooden rear end part is` connected whereby at least one of said end parts can be readily detached from and attached to said' center part. The edges of the center part of the sld which are particularly subjected to wear .are thus of Ametal or a material which isharder than wood and lasts longer. To the center part of the ski according tothe present invention the harness can be more con-4 veniently and more rigidly and reliably connected than to an al1-wood ski. v

Further and other objects of the present in vention will be hereinafter Aset forth in the accompanying specification and claims land shown in the drawings which, by way of illustration, show what I now consider to be bodiments of my invention.

Fig. 12 is a top view of the ski shown in Fig. 11..A y I Fig. 13 isa viewvtowards the rear end of the` center part of the ski'shown in Figs. 11 and 12,.

Referring morepa'rticularly to Figs. 1 to 4 'of' lthe drawings, I is the center part, 2 is the pointed fore or front endrpartand 3 is the rear end part ofa "ski according to the present invention. The fore and rear end parts 'are generally made of wood whereas the center. part ismade of a material more lasting than wood, for example. metal.

In the embodimento'f Vmy invention shown inthe parts. The thickness of the center part maybe somewhat reduced Where the shoe ofy the skier is tied to the center part by means of` the har'- ness. The upper edges of the center part I areV left away at both ends so that tongues "landl II are formed whichfare piolvidedwithgrippirigjv means or hooks I2 and I3 respectively. ".I'he'` top sides of the inner ends of the wooden end" parts are provided with lock plates I4 and Ii'iV onto which the hooked `ends of the upper parts drawings, part I is a hollowsheath-llke body of part I, i. e., the tongues I0 and II snap when parts 2,. and 3 are pushed far enough into the` center part I; falling of parts 2 and 3 out of the center part is thereby prevented.

The tongues III and II are pressed to parts 2 and 3 and to the plates I4 and I5 by means of the eccentrics `4 and 6 which form the fulcrum `ends of levers 5 and 5' respectivelywhich levers l swing about pivots `which are supported by the eyes I6 and I'I which are partof the center piece I. By turning levers 5 andupwards the pressure on tongues IIIv and II is relieved 'and parts 2 and 3 may be freed from the hooks I2 'and I3 pulled out `of the center piece.`

The center piece may also be made ofv pressed lmetal instead of being cast. vThe elasticity of such `center pieces is greater and theyre'duction of the cross section of the plug ends otparts 2 and'3 is smaller so that these ends are stronger. Since the -center part is made of light metal or otherlight material the ski according to the present invention is justas light as any other rear end are ush with those of'thefrearlpartl of the ski and the shoe is permanently connected thereto by means of lateral screws-24.

The ,lower ,parttlof theel-10e Projects beyond the main rear end ofthe shoe and isset into the wood, so. .that its surface .is vvflush with ythe running surface of the ski. Inorder, toproduce a continuous Wooden running s11lifaca-a layer oi wod is held to the'f-loweig..surface of the shoe by means of the dove `tail tongues,3l and ,the

screws` 28.-', .'Iihe.v wooden liriing25V is provided with af groove '3 2, which,g .continues in' groovesA 33 and 34;at the fore end y22.-.ancl of the rear end 2310iA the. ski respectivelyvfrhe edges of the. hard shoeprevent wearingoff off the edges of the running .surf,acelofthe/ski. yThe fore part 22 of'. the ski i-s made stouter at the part-adjacent to ,the shoe, 2| so that plug- I8 has approximately the same .cross `sectional dimensions as has thei unrestricted rear zpart- 23 `of the ski.l

Tothe upperr surface of part 22 an eccentric lever-y 21./is fulcrumed, said lever having a buckle 28 movably connected thereto whichbuckle can be'hooked into the hook 29 connected to shoe 2|.

The rear end of the plug |8 is slightly tapered 'so that vthe plug is forced into the shoe and waggling is prevented.

In order to dismantle the ski, eccentric lev'er 21 is moved counterclockwise whereby buckle 28 is freed from the hook 9 and the fore end 22 of the ski can be pulled out of shoe 2| which remains fixed to the rear end 23 of the ski.

The harness is fixed to the shoe 2| in the same manner as is customary with the'conventional skis.

In the embodiment of the present invention illustrated in Figs. 11 to 13 no wooden lining is required at the .bottom surface of the shoe. 'I'he shoe 35 is of substantially U shaped cross sectional conguration and is provided at its lower end With inwardly extending flanges 36 between the inner edges offwhich is suiiicient space for a wooden ski surface. The end plug 31 of the fore 4part of the ski is formed by a slight reduction of the width of thezski and lateral niches or recesses 40 at the bottom of the ski and extends into the shoe 35. The lateral recesses 40 may be provided-'with plate springs4| which resiliently press theplug end to the shoe. The rear end of plug31 may have a projecting part 42 which` maybe made, for example, of leather.

The plug 38 of the rearl end of the ski is formed by a reduction of the .width of theski and,` by taking some material. oi the upper part of the ski. Plug 38 is -permanently connected with the shoe 35, for example, by means of screws 39y which may be used at 'the same time for fixing the jaw part 54 of the harness to the center part 35. From the fore end of plug 38 a plate spring u 43 projects which, when theski is assembled,

and construction, sho

abuts against part 42. with a recess 44 in member 38.

The llatter part matches-f For pulling the fore part 45 ofthe ski` into Lever `46'swingably 'carries the buckle or bracket member 43 which can be hooked into hook 49, the

latter being rigidly connected with the shoe 35.

'I'he brackets 50 carrying fulcrum 41 may be directly connected with'a longitudinal base plate `which is screwedor otherwise rigidly connected with "the fore part of the ski. Base plate 5| may be `used-for carrying a, plurality of half-moon 'shaped members 5,2around which the flexible cable 61 'ness ofthe harness can be laid as 'shown in Fig;3 12.
